Simple Inventory System in Python using DB Browser SQlite with Source Code

1. To begin, you will need to install the `sqlite3` module, which allows Python to interact with SQLite databases. You can do this by running `pip install sqlite3` in your command prompt or terminal.

2. Once you have installed the module, you can import it into your Python script and establish a connection to an SQLite database file. You can use the `connect()` method from the `sqlite3` module to achieve this.

3. Next, you can create a table within the database to represent your inventory. Decide on the fields you want to include, such as product name, quantity, price, etc., and define their data types accordingly.

4. With the table created, you can now write functions to perform inventory operations. These functions might include adding new products, updating quantities, retrieving product information, and deleting products.

5. Consider implementing error handling to address potential issues, such as trying to add a product that already exists or accessing a product that is not present in the inventory.

6. Additionally, you can create a user interface to provide a graphical representation of your inventory system. This can be done using libraries such as tkinter or PyQt. The interface should allow users to perform various inventory operations through buttons or menus, and display relevant information when needed.
